Abstract
In our previous paper, we studied a model of location based service (LBS) in a wireless sensor network. In this paper, we study a post-data process of the motion-trace data of an object with the proposed model, which is based on the aforementioned model. Compared with the one which uses a single model to describe the motion traces, the Interacting Multiple Model (IMM) with Unscented Kalman lter (UKF) provides a powerful framework when tracking a motion object with the position service in a LBS tracking system. We study an UKF based algorithm applied to smooth the trace of a positioned object. The implementation of the locating device and the experiments conducted in the real applied scenarios are described in this paper.
